Intelligent protection is based on the big data processing capabilities of Alibaba Cloud. Through the intelligent analysis engine, it can learn business traffic baselines and dynamically adjust protection models to help you detect and block attacks in a timely manner, such as malicious bots and HTTP flood attacks.

After intelligent protection is disabled, the automatically issued intelligent rules are cleared instantly.
